The root problem is that the types are mixed up in the header map. 
A map value is either a String or a list containing Strings - hopefully. 
This mixture might save a few bytes of memory but causes all kind of 
programming headache. You always have to find out which kind of value 
your dealing with and act upon it appropriately. This is - as the 
above-quoted bug message demonstrates - error-prone and time-consuming.

Is there a chance to change that? I'd like to see the second variant, 
i.e. get rid of the String-only stuff.

Best regards
